Many devices go thorough a reset/test sequence when powered on that they don't necessarily go through when it is rebooted. Also ram gets scrambled when the device is powered off.

As I've said elsewhere, I had battery life issues on a couple of iOS devices after an upgrade until I turned them off and back on. I have no solid data to back it. But it's what I've observed. And for all that it takes less than a minute, it can't hurt.
